In this article, we would like to show you how to use RIGHT JOIN in MySQL.

Quick solution:

SELECT `column1`, `column2`, `columnN`
FROM `table1`
RIGHT JOIN `table2`
ON `table1`.`column_name` = `table2`.`column_name`;

Practical example

To show how the RIGHT JOIN works, we will use the following tables:

Tables in the database
Tables in the database

Note:

At the end of this article you can find databases preparation SQL queries.

Example 

In this example, we will select all information about users and departments, even when there are no users assigned to a department.

Query:

SELECT * FROM `users`
RIGHT JOIN `departments` 
ON `departments`.`id` = `users`.`department_id`;

Output:

MySQL - RIGHT JOIN result - HeidiSQL
MySQL - RIGHT JOIN result - HeidiSQL

Database preparation

create_tables.sql file:

CREATE TABLE `departments` (
	`id` INT(10) UNSIGNED NOT NULL,
	`department_name` VARCHAR(50) NOT NULL,
	`location` VARCHAR(50) NULL,
	PRIMARY KEY (`id`)
);

CREATE TABLE `users` (
	`id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
	`name` VARCHAR(50) NOT NULL,
	`surname` VARCHAR(50) NOT NULL,
	`department_id` INT(10) UNSIGNED,
	PRIMARY KEY (`id`),
	FOREIGN KEY (`department_id`) REFERENCES `departments` (`id`)
)

insert_data.sql file:

INSERT INTO `departments`
	(`id`, `department_name`, `location`)
VALUES
	(1, 'Sales', 'New York'),
	(2, 'Finance', NULL),
	(3, 'HR', 'Atlanta'),
	(4, 'Purchase', 'New Orlean'),
	(5, 'Operations', 'Boston');

INSERT INTO `users`
	( `name`, `surname`, `department_id`)
VALUES
	('John', 'Stewart', 1),
	('Chris', 'Brown', 2),
	('Kate', 'Lewis', 3),
	('Ailisa', 'Gomez', NULL),
	('Gwendolyn', 'James', 2),
	('Simon', 'Collins', 4),
	('Taylor', 'Martin', 2),
	('Andrew', 'Thompson', NULL);
